How to Fix CVE-2019-5415

To remediate this vulnerability, upgrade all affected Serve dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

serve fixed: 7.0.0 
npm install serve@7.0.0
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

npm ls serve

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2019-5415, inspect your project dependencies using npm:

npm ls serve

Analyze the terminal output to locate any version of Serve in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 7.0.0), your application is affected.

Note: The npm ls serve command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-548: Exposure of Information Through Directory Listing, where the product inappropriately exposes a directory listing with an index of all the resources located inside of the directory. In Serve, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

Versions of `serve` prior to 7.0.1 are vulnerable to Path Traversal. Explicitly ignored folders can be accessed through if the path contains a `/./`, which allows attackers to access hidden folders and files. ## Recommendation Upgrade to version 7.0.1 or later.
